Inverse Simulation of Radiative Thermal Transport

Computer Graphics Forum, EarlyView.
Abstract The early phase of urban planning and architectural design has a great impact on the thermal loads and characteristics of constructed buildings. It is, therefore, important to efficiently simulate thermal effects early on and rectify possible problems.

Lipschitz Pruning: Hierarchical Simplification of Primitive‐Based SDFs

Computer Graphics Forum, EarlyView.
Abstract Rendering tree‐based analytical Signed Distance Fields (SDFs) through sphere tracing often requires to evaluate many primitives per tracing step, for many steps per pixel of the end image. This cost quickly becomes prohibitive as the number of primitives that constitute the SDF grows.

Learning Metric Fields for Fast Low‐Distortion Mesh Parameterizations

Computer Graphics Forum, EarlyView.
Abstract We present a fast and robust method for computing an injective parameterization with low isometric distortion for disk‐like triangular meshes. Harmonic function‐based methods, with their rich mathematical foundation, are widely used. Harmonic maps are particularly valuable for ensuring injectivity under certain boundary conditions. In addition,

State‐of‐the‐art Report in Sketch Processing

Computer Graphics Forum, EarlyView.
Abstract Sketches are a powerful and natural form of communication and are used in numerous systems for modelling, animation, shape retrieval, and editing. Despite their popularity, rough sketches — whether raster or vector, 2D or 3D — are often too complex and imprecise to be used directly and thus need special processing.

Terrain descriptors for landscape synthesis, analysis and simulation

Computer Graphics Forum, EarlyView.
Abstract Synthetic landscape generation is an active research area within Computer Graphics. Algorithms for terrain synthesis and ecosystem simulations often rely on simple descriptors such as slope, light accessibility, and drainage area. Typically, the results are assessed from a perceptual standpoint, focusing primarily on visual plausibility. Other

Survey on Modeling of Human‐made Articulated Objects

Computer Graphics Forum, EarlyView.
Abstract 3D modeling of articulated objects is a research problem within computer vision, graphics, and robotics. Its objective is to understand the shape and motion of the articulated components, represent the geometry and mobility of object parts, and create realistic models that reflect articulated objects in the real world.

Visually Assessing 1‐D Orderings of Contiguous Spatial Polygons

Computer Graphics Forum, EarlyView.
Abstract One‐dimensional orderings of spatial entities have been researched in many contexts, e.g. spatial indexing structures or visualizations for spatiotemporal trend analysis. While plenty of studies have been conducted to evaluate orderings of point‐based data, polygonal shapes, despite their different topological properties, have received less ...

Voronoi Cell Interface‐Based Parameter Sensitivity Analysis for Labeled Samples

Computer Graphics Forum, EarlyView.
Abstract Varying the input parameters of simulations or experiments often leads to different classes of results. Parameter sensitivity analysis in this context includes estimating the sensitivity to the individual parameters, that is, to understand which parameters contribute most to changes in output classifications and for which parameter ranges ...

Fast HARDI Uncertainty Quantification and Visualization with Spherical Sampling

Computer Graphics Forum, EarlyView.
Abstract In this paper, we study uncertainty quantification and visualization of orientation distribution functions (ODF), which corresponds to the diffusion profile of high angular resolution diffusion imaging (HARDI) data. The shape inclusion probability (SIP) function is the state‐of‐the‐art method for capturing the uncertainty of ODF ensembles. The

Rapid riparian ecosystem decline in Rocky Mountain National Park

Conservation Biology, EarlyView.
Abstract Understanding the drivers of ecosystem collapse is critical for resource management, particularly for protected areas mandated to preserve biodiversity. In Rocky Mountain National Park, Colorado, tall willows (Salix spp.) dominated riparian vegetation, and a beaver–willow state was the natural ecosystem type in the Colorado River headwaters ...
